| Abstract: | Crystals of SrY2O4 (space group Pnam ) were examined by high-temperature powder X-ray diffractometry to determine the changes in unit-cell dimensions with temperature. The individual cell dimensions linearly increased with increasing temperature up to 1473 K. The expansion coefficients (K−1) were 1.263(8) × 10−5 along the a- axis, 7.46(6) × 10−6 along the b- axis, and 9.93(10) × 10−6 along the c- axis. The coefficient of mean linear expansion was 1.001(8) × 10−5 K−1. |
